[0037] In this embodiment, if Figure 1 and Figure 2 As shown, a rice length selector includes a selector body 1, on which a dust removal assembly 2 is installed. The dust removal assembly 2 is used to reduce the entry of rice bran dust into the inner cavity of the selector body 1. The dust removal assembly 2 includes a feed pipe 21, a storage shell 22, a mounting seat 23, a bolt 24, a fan 25, a stirring member 26 and a dust collecting member 27. The feed pipe 21 is used to introduce rice into the cavity of the selector body 1. The air outlet of the storage shell 22 is connected to the feed pipe 21. The mounting seat 23 is connected to the air inlet of the storage shell 22 through the bolt 24. The air outlet of the fan 25 is connected to the mounting seat 23. The stirring member 26 is used to prolong the residence time of rice in the feed pipe 21. The dust collecting member 27 is used to adsorb dust in the rice.

[0038] Therefore, when the rice enters the concentrator body 1 through the feed pipe 21, the stirring member 26 turns the rice over, thereby separating the impurities from the rice pile. The fan 25 is started and the fan 25 sucks the impurities into the storage shell 22. At the same time, the dust collecting member 27 absorbs some of the impurities, and the other part of the impurities is retained in the trapezoidal storage bin of the storage shell 22, thereby reducing the impurities entering the concentrator body 1.

[0039] Specifically, the rice sorting machine body 1 is used to sort rice. The feed pipe 21 is processed with a long strip through groove, and the storage shell 22 is processed with a downwardly protruding trapezoidal storage bin. The dust sucked out by the fan 25 can be stored in the trapezoidal storage bin. The mounting base 23 is used to install the fan 25. The design of the bolt 24 facilitates the disassembly of the mounting base 23 and the storage shell 22.

[0040] For example, the shape of the storage compartment in the storage shell 22 is not specifically limited and may also be conical. The mounting seat 23 and the storage shell 22 may also be connected using other connection methods.

[0041] In some embodiments, as Figure 4 As shown, the dust collecting part 27 includes a sealing plug 271, a sleeve 272 and a dust collecting filter element 273. The outer periphery of the sealing plug 271 is connected to the inner thread of the storage shell 22, the top of the sleeve 272 is connected to the sealing plug 271, and the dust collecting filter element 273 is fixedly connected to the outer periphery of the sleeve 272.

[0042] Specifically, the sealing plug 271 is connected to the top of the storage shell 22 through a thread. The storage shell 22 is processed with an internal thread that is compatible with the sealing plug 271. The sleeve 272 drives the dust collection filter 273 to extend into the feed pipe 21. The dust collection filter 273 is installed at the top of the feed port of the feed pipe 21, and then the dust collection filter 273 absorbs dust.

[0043] Based on this, the sealing plug 271 and the storage shell 22 are detachably connected, thereby facilitating the replacement of the dust filter element 273 , and the sleeve 272 is used to determine the use position of the dust filter element 273 .

[0044] In some embodiments, as Figure 2 As shown, the stirring member 26 includes a transmission shaft 261, a servo motor 262 and a flap 263. The transmission shaft 261 is connected to the feed pipe 21 through a bearing, the output end of the servo motor 262 is connected to the transmission shaft 261, and the flap 263 is located in the cavity of the feed pipe 21. The flap 263 is symmetrically distributed about the transmission shaft 261.

[0045] Specifically, the transmission shaft 261 is installed at the bottom of the feed port of the feed pipe 21, the servo motor 262 is used to drive the transmission shaft 261 to rotate, and two flaps 263 are provided. The rotation of the flaps 263 increases the retention time of rice in the feed pipe 21.

[0046] In some embodiments, as Figure 5 As shown, a feed assembly 3 is installed in the feed pipe 21, and the feed assembly 3 is used to transfer the rice discharged from the external separation screen to the cavity of the feed pipe 21. The feed assembly 3 includes a discharge shell 31, a rotating shaft 32, a feed tray 33 and a locking member 34. The discharge shell 31 is connected to the feed port of the feed pipe 21, the feed tray 33 is hinged to the discharge shell 31 through the rotating shaft 32, and the locking member 34 is used to limit the rotation of the rotating shaft 32.

[0047] Specifically, an inclined chute is machined in the lower shell 31, which is conducive to the rice sliding into the feed pipe 21. Two rotating shafts 32 are provided, and a cavity is machined in the feed tray 33. The feed tray 33 is used to connect with the external grading screen.

[0048] In some embodiments, as Figure 5 As shown, the locking member 34 includes a limit plate 341, an arc plate 342 and a positioning pin 343. The limit plate 341 and the rotating shaft 32 are fixedly connected at one end extending out of the discharge shell 31. The arc plate 342 is connected to the limit plate 341 through the positioning pin 343, and the arc plate 342 and the discharge shell 31 are fixedly connected.

[0049] Specifically, threaded holes adapted to the positioning pins 343 are machined in the limiting plate 341. The threaded holes are evenly spaced along the outer circumference of the limiting plate 341, thereby controlling the angle between the feed tray 33 and the discharge shell 31. The outer wall of the positioning pin 343 is machined with threads, and the arc plate 342 is used to determine the use position of the positioning pin 343.

[0050] In addition, the locking member 34 can also be replaced with other limiting structures to meet the requirements of braking the rotating shaft 32 and fixing the tilt angle of the feed tray 33.

[0051] In some embodiments, as Figure 2 As shown, an opening and closing member 221 is installed at the bottom of the storage shell 22. The opening and closing member 221 includes a sealing plate 221a and a threaded pin 221b. The sealing plate 221a is used to close the bottom opening of the storage shell 22. The sealing plate 221a is connected to the storage shell 22 through the threaded pin 221b.

[0052] Specifically, four threaded pins 221 b are installed in the sealing plate 221 a . The openable design of the sealing plate 221 a is conducive to discharging impurities retained in the storage shell 22 .

[0053] In some embodiments, as Figure 3 As shown, a dustproof net 231 is fixedly connected to the bottom end of the mounting base 23 , and the dustproof net 231 is used to prevent dust from entering the fan 25 .

[0054] Specifically, the dustproof net 231 and the air outlet of the fan 25 are located on the same vertical line, and the design of the dustproof net 231 prevents dust from entering the fan 25.

[0055] In some embodiments, as Figure 2 As shown, a mesh plate 263 a is fixedly connected to the flap 263 .

[0056] A mesh plate 263 a is fixedly connected to each flap 263 , and some broken rice can directly enter the feed pipe 21 through the mesh plate 263 a .

[0057] In some embodiments, as Figure 4 As shown, a handle 271 a is fixedly connected to the top of the sealing plug 271 , and the handle 271 a is used to rotate the sealing plug 271 .

[0058] The handle 271 a is processed with grinding grooves, and the handle 271 a makes the rotation of the sealing plug 271 more convenient.

[0059] In some embodiments, as Figure 4 As shown, the dust filter element 273 is made of non-woven fabric material.

[0060] For example, the dust filter element 273 is made of non-woven fabric material, and the through holes on the surface of the non-woven fabric material make it easier to absorb dust.

[0061] The working principle of this application is described below with a preferred embodiment:

[0062] The feed tray 33 is rotated in the lower shell 31 by the rotating shaft 32, and the tilted feed tray 33 is connected to the grading screen. Then, the positioning pin 343 in the arc plate 342 is rotated, and the positioning pin 343 is inserted into the corresponding threaded hole in the limit plate 341, thereby fixing the tilt angle of the feed tray 33. The rice enters the feed pipe 21 along the feed tray 33 and the limit plate 341, and the servo motor 262 is started. The servo motor 262 drives the transmission shaft 261 to rotate, and the transmission shaft 2 61 drives the two flaps 263 to rotate, and then the flaps 263 break up the falling rice strands. At the same time, the fan 25 is started, and the fan 25 draws impurities into the storage shell 22. The dust is adsorbed by the dust filter 273 on the outer wall of the sleeve 272. Part of the dust is blocked by the dustproof net 231 and retained in the trapezoidal storage bin at the bottom of the storage shell 22. The threaded pin 221b and the sealing plate 221a are rotated to separate, and then the dust retained in the storage shell 22 is cleaned.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
